Patented Nov. 6, 1906.

Application filed August 9, i905. Serial No. 273,416.

Be it known that I, GEORGE F. MOOAHEY,

a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Tipping Lacings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for tipping lacings, and has for its object to provide means for forming the lacing-tip in a die and severing the tipped portion while in the die.

A further object of the invention is that said die shall travel, and in traveling it carries the severed tip from the point where it is formed to the point when it is drop ed. At the same time it measures off the ength of the lacing and gives the lacing material a continuous feeding motion.

A further object is to provide means for severing the tipped portion of the lacing and for overcoming the difiiculties heretofore experienced in severing said tipped portion, due to the stretching of the lacing and the backlash of the mechanism when measuring off the lengths of the lacing.

A further object is to increase the speed of production.

In carrying out my invention two tippingdies are employed, each being mounted in oppositely-extending arms mounted to rotate around a common center. The braid is fed to the first set of dies at the end of the arm, and the tip is formed therein and severed as said arm is traveling a half-revolution around said center. At the time this die is opened to deposit the finished lacing the second die in the opposite arm is receiving the braid to form another tip thereon, and so it continues, first one set of dies and then the other working on the braid as it is drawn in by the traveling arms. It will be seen that by this method the braid is drawn continuously, being gripped by the traveling dies, and the length of the lacing is controlled and determined by the positioning of the adjustable reel-pins around which the braid is drawn.

By causing the die to travel the tip is completely formed and severed while the length of the lacing is being measured off,

thereby allowing ample time in which'to perform the operation, avoiding the wear and tear of quick reciprocation. The severing of the'tipped portion at its center is thus assured, and the feed of braid is continuous,

forming substantially a rotary process by.

which the production of the machine is greatly increased.

The invention consists of other novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the appended claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

' In the accompanying drawings, Figure i is a side elevation of my device, partly in section, to better illustrate the actuating mechanism. Fig. 2 is a plan of the device, showing the two rotatable ,arms with the adjustable reel-pins. Fig. 3 is an enlarged elevation sectioned through one of the arms, showing the dies in the closed position and the cutter in full lines as raised and in dotted lines as having entered the die and severed the tip. Fig. 4 is an enlarged view showing the dies and perforator in the open position ready to receive the tipping metal. Fig. 5 shows a perspective view of the dies drawn apart and illustrating the same as being split or recessed to receive the cutter. Fig. 6 is a detail plan view of the inner end of the die slide-arm, illustrating the meansfor the endwise adjustment of the same. Fig. 7 shows a detail of the metal roll, illustrating the covering material as being split or wound in two separate rolls. Fig. 8 shows a lacing tipped with two separate pieces of metal, with a space between them where the same is to be severed. Fig. 9 illustrates a lacing in the die being severed by the cutter. Fig. 10 is a detail illustrating the construction of one of the adjustable reel-pins.

Referring to the drawings, at 1 is the bed of the machine, supported on the legs 2 2. On this bedis the boss 4, and extending from the same is the fixed upright shaft 5. The oppositely-extending arms 6 6 are arranged to rotate around this upright shaft and are supported from the boss 4 through the hub 7 of the gear 8, to which gear-hub said arms 6 6 are bolted. The rotary motion is imparted to said gear and arms from a source of power (not shown) through pulleys 9, shaft 10, and

pinion 11.

As the mechanism on one end of the arm is an exact duplication of that on the opposite end, it will be necessary in the description to refer to one end only.

The covering for the tips 14 on the lacings may be of any desired material, but are preferably formed of thin sheet metal, that is fed to the dies from the roll 12, that is suspended beneath the arm 6 on the bracket 13.

The die in which the tips are covered and compressed is made in two parts 15 and 16. The portion 16 is fixed to the plate 21 on the arm and may be set up or adjusted endwise by the set-screw 22, and the portion 15 is mounted in a longitudinally-sliding bar 17. On the inner end of this bar is an endwiseadjustable shoe 21 (see Fig. 6,) that may be set by the adjusting-screw 22 to regulate the throw or positioning of the die 15.

The bar is carried inward by the engagement of the upwardly-extending lug or boss 18 with the cam-groove 19, and said bar is carried outward by contact with the edge of cam 20. Both of these cams 19 and 20 are fixed to said upright shaft, and as the said die-bar is carried around the cams it is actuated to move inward to open the die and outward to close thesame.

The metal covering-strip before it is formed into the tip is perforated by pins 23, carried by a longitudinally-movable bar 24:, whereby the tip is prevented from slipping off the lacing. This pin-bar has an endwise adjustment in the screw 25, the head of which rests against the shoe 21, by the movement of which shoe the pin-bar is carried forward, the same being returned by the tension of spring 26.

An important feature of my invention is the cutting of the tips while held in the die, to accomplish which the die is split or recessed at 27 and 28 for the purpose of receiving the cutter 29. in any desired form; but 1 preferably use a thin sharp-edged disk and rotate the same. The disl: may be rotated through the fixed gear 30, pinion 31, (that is rotated by being carried around said geary) pulleys 32, 33, and 3a, and belts and 86. The cutter is preferably mounted on an arm 37, said arm being pivoted on the pin 38, and is raised and lowered by means of the teeth 39, that are cut on the under side of its hub, engaging those on the endwise-movable rack 10. (See Fig. 3.) This rack is actuated by contact of the roller ll. (pivoted in its end) with the edge of the fixed cam 42, and as this rack is carried around said cam by the travel of arm 6 the cutter is allowed to drop and perform its operation and is raised again at its proper time through the movement of said rack.

In feeding the covering to the dies the two feed-rolls 43 and it are employed to grip the same and carry it forward. Roll and is actuated to rotate at intervals through the me- This cutter may be madedium of the fixed cam 45, the cam-actuated sliding bar 46, the swinging depending pawl 47, the ratchet 48, and the connecting-rod 49. The cam-bar is pressed outward to actuate the feeding mechanism and is returned by the action of the spring 50.

At 52 52 (see Fig. 2) are radiating members fixed to and carried by the arms 6. In the outer ends of these members are upwardlyextending pins 53, and'said ins are adjustable either toward or from t e center in the radial slots 54 in said members. As the lacing is being drawn in by the rotating arm 6 the material naturally lies against said pins,

and the length of the lacing is very readily 8o controlled by simply adjusting these pins either toward or from the center.

The operation of the machine may be further described as follows: Two oppositelyextending arms are arranged to be rotated in a horizontal plane about a fixed upright shaft, one arm carryin a duplicate mechanism of the other arm. utomatic mechanism is arranged to feed a covering material 51 from a roll 12;, carried by said arm. This covering material is fed up to a die, is perforated to make the same adhere more closely to the fabric, and is out off, Wound around, and compressed onto the lacing material by means of the dies 15 and 16, which are constructed so as to coil the covering about the lacing and compress it upon the same as said dies are being brought together. After the covering has been applied and while that por tion. is still held in the die a cutter is actuated I00 to pass into the die and sever the covered portion. The feeding of the covering, perforating, and the operation of the die and cutter are all operated while the arms are in motion. The lacing material 55 is .led from the I05 can 56 through the guide-eye 57 to the traveling dies 15 and 16. Any desired means may be employed to insure the material being led to and deposited in these dies. l have shown a spring-wire eye 58 for this purpose that is I10 arranged to be sprung back or withdrawn automatically as the die approaches and jump forward. and deposit the material in thejaws of the die at the proper time. As tne tip is being formed and severed it is being carried I15 from the feeding-point to the point of delivery at the opposite side of the machine, where the die is withdrawn and the tip released. Any suitable means may be employed to en gage the finished lacing at this point and con- 1 '20 vey it away or deposit it in any convenient place to be labeled or bundled.

The advantages of my invention will be at once apparent to those skilled in the art to which it appertains. noted that T have provided means whereby the lacing may be tipped and the tipped portion severed while still held in the formingdies. It will be further observed that T have provided means whereby the lacing is meas- 1 go It will be particularly r2 5 ured off simultaneously with the tipping operation and without interfering with the tipping operation. It will also be observed that I have overcome all difficulties incident to the stretching of the lacing and the backlash of the mechanism in the tipping, cutting, and measuring-off operations.
